Coronavirus/COVID-19 Notice

Thank you in advance for your support during the Coronavirus/COVID-19 pandemic. We are implementing policies and procedures consistent with nationwide measures to protect our patients, ourselves, and to help limit the spread of the virus. As you know, this virus has already dramatically affected the health of people around the world. Our goal is to minimize risks for exposure within our clinics, standardize processes for identifying and evaluating persons potentially affected by the virus, coordinate care with local health systems, and provide a base level of readiness that can be built upon as this pandemic evolves. Implementing telemedicine encounters, limiting the flow and number of visitors, and extending intervals between less urgent visits are examples of some measures we are implementing. While doing this, we will continue to provide essential care to our patients with cancer, blood, and other medical disorders that require continued treatment and monitoring. We believe this is best for our patients and will also help reduce additional burdens to the already stressed health care system. We will continue to revise our policies and procedures as necessary. Once again, I thank you in advance for supporting our efforts.

Sincerely,
Justin Floyd DO, FACOI
President, Cancer Care Specialists of Illinois
